Ok, forget all about that crack with the Launcher.exe! I dont know what it is meant to be, it may even be a fake file!
Now even tho 'GeorgeK' is correct in saying you do not need a crack to play Doom3 or Resurrection of Evil, there is indeed a crack for ROE!
This file: Doom 3: Resurrection of Evil v1.2 [ENGLISH] Fixed EXE by 'Mint' found at GCW
here, (Scroll down to it) bypasses the call-home behaviour during key validation, thats all! This is the same as using a firewall to block Doom 3 from connecting to the internet! When using this crack you will still be able to play both Doom3 and ROE without the need of the Discs in the drive!
I hope this clears things up for you!
